Some online sources that provide meat-cooking temperature charts are the United States Department of Agriculture, Food Network and Food Safety. The USDA site provides a meat-cooking temperature chart that can be printed. The chart provides the minimum internal temperature that different meat products should have before their consumption; this is to prevent any possible food-borne illnesses associated with eating either raw or undercooked meats.
The other two websites present the same information on minimum internal temperatures for meats and other food products. For example, ground meat should have an internal temperature of 160 degrees Fahrenheit before it is safe to serve. A food thermometer can accurately tell when meat is cooked at these specified temperatures.
All three sites provide additional information on the importance of cooking food to at least these minimum internal temperatures to prevent food poisoning from bacteria in food. For example, cooking ground beef to its specified minimum internal temperatures destroys E. coli bacteria.
